According to Osho, masters invoke other awakened ones out of a love that blossoms when worldly attachment falls; the guru is a door linking you to the living lineage, not a cage. One light shines through many lamps, so citing many buddhas frees seekers from fixation on one style and opens the whole sky of awakening.
They point to many wise ones so you see the same light everywhere, don’t cling to one person, and learn to be free.
